BACKGROUND

The present invention generally relates of the fields of networkedcomputerized industrial control, automation systems and networkedcomputerized systems utilized to monitor, log, and display relevantmanufacturing/production events and associated data, and supervisorylevel control and manufacturing information systems. Such systemsgenerally execute above a regulatory control layer in a process controlsystem to provide guidance to lower level control elements such as, byway of example, programmable logic controllers or distributed controlsystems (DCSs). Such systems are also employed to acquire and managehistorical information relating to such processes and their associatedoutput. More particularly, the present invention relates to ahuman-machine interface (HMI) system for a manufacturing and/or processcontrol system such as supervisory control and data acquisition (SCADA)and/or manufacturing execution systems (MES). Such systems generallyexecute above/outside of a control layer of a manufacturing/processcontrol system to record production events and related event data and toprovide guidance to lower level control elements such as, by way ofexample, programmable logic controllers.

Industry increasingly depends upon highly automated data acquisition andcontrol systems to ensure that industrial processes are run efficiently,safely and reliably while lowering their overall production costs. Dataacquisition begins when a number of sensors measure aspects of anindustrial process and periodically report their measurements back to adata collection and control system. Such measurements come in a widevariety of forms. By way of example the measurements produced by asensor/recorder include: a temperature, a pressure, a pH, a mass/volumeflow of material, a tallied inventory of packages waiting in a shippingline, or a photograph of a room in a factory. Often sophisticatedprocess management and control software examines the incoming data,produces status reports, and, in many cases, responds by sendingcommands to actuators/controllers that adjust the operation of at leasta portion of the industrial process. The data produced by the sensorsalso allow an operator to perform a number of supervisory tasksincluding: tailor the process (e.g., specify new set points) in responseto varying external conditions (including costs of raw materials),detect an inefficient/non-optimal operating condition and/or impendingequipment failure, and take remedial actions such as move equipment intoand out of service as required.

Typical industrial processes are extremely complex and receivesubstantially greater volumes of information than any human couldpossibly digest in its raw form. By way of example, it is not unheard ofto have thousands of sensors and control elements (e.g., valveactuators) monitoring/controlling aspects of a multi-stage processwithin an industrial plant. These sensors are of varied type and reporton varied characteristics of the process. Their outputs are similarlyvaried in the meaning of their measurements, in the amount of data sentfor each measurement, and in the frequency of their measurements. Asregards the latter, for accuracy and to enable quick response, some ofthese sensors/control elements take one or more measurements everysecond. Multiplying a single sensor/control element by thousands ofsensors/control elements (a typical industrial control environment)results in an overwhelming volume of data flowing into the manufacturinginformation and process control system. Sophisticated data managementand process visualization techniques have been developed to handle thelarge volumes of data generated by such system.

Highly advanced human-machine interface/process visualization systemsexist today that are linked to data sources such as the above-describedsensors and controllers. Such systems acquire and digest (e.g., filter)the process data described above. The digested process data in-turndrives a graphical display rendered by a human machine interface.Examples of such systems are the well-known Wonderware INTOUCH.RTM.human-machine interface (HMI) software system for visualizing andcontrolling a wide variety of industrial processes and the ArchestrA™(e.g., the application server or AppServer for INTOUCH™) comprehensiveautomation and information software open architecture designed tointegrate and extend the life of legacy systems by leveraging thelatest, open industry standards and software technologies.

An INTOUCH HMI process visualization application includes a set ofgraphical views of a particular process. Each view, in turn, comprisesone or more graphical elements. The graphical elements are “animated” inthe sense that their display state changes over time in response toassociated/linked data sources. For example, a view of a refiningprocess potentially includes a tank graphical element. The tankgraphical element has a visual indicator showing the level of a liquidcontained within the tank, and the level indicator of the graphicalelement rises and falls in response to a stream of data supplied by atank level sensor indicative of the liquid level within the tank.Animated graphical images driven by constantly changing process datavalues within data streams, of which the tank level indicator is onlyone example, are considerably easier for a human observer to comprehendthan a stream of numbers. For this reason process visualization systems,such as INTOUCH, have become components of supervisory process controland manufacturing information systems.

The INTOUCH HMI empowers users to quickly and easily develop customgraphical views of their processes. Users can develop graphics with avariety of tools in WONDERWARE's WindowMaker graphical view editingprogram, which includes: standard graphical components, displays,animations, bitmap images, ActiveX controls, a graphics librarycontaining thousands of preconfigured industrial images, SmartSymboltechnology, tag definitions, I/O configuration, binding, scripts, alarmand history configurations.

Typically, users use INTOUCH to develop supervisory control and dataacquisition systems applications and HMI applications. Users use INTOUCHto develop their custom applications to visualize plant data and statusin a real-time manner by interfacing HMI software to sources of plantequipment, such as PLCs. To develop INTOUCH applications, users need todefine real-time data connectivity to PLC, tag database, graphicsdevelopment, graphics animation and alarms definition.

HMI applications have been used for supervisory controls, panels andcontrols. HMI applications are developed using HMI applicationdevelopment utilities that allow users to create a specificconfiguration (referred to herein as an HMI application) for their ownspecific need/application. Therefore, HMI development utility softwareis designed and developed by a software vendor. Thereafter, the HMIdevelopment utility is used by end users to render a potentially vastnumber of HMI applications including views and associated functionalityfor particularized needs of specific process automation andmanufacturing information installations.

While it is important to innovate and provide new technologicalofferings, it is also important to provide a migration path fromexisting technologies to the new offerings. HMI technologies and thesystems within which they operate are constantly evolving. Typicalmanufacturing automation HMI application definitions consist of a numberof configured elements including: displays, tags, I/O binding, PLCconnections, animations, scripts, alarms and events, historyconfiguration. Therefore evolution of HMI technologies presents apotential problem for users that have created a large number of HMIapplications using existing technologies.

To encourage users to adopt newer technologies, HMI utility developershave provided migration paths that enable users to leverage theirpreviously created HMI applications in systems that adopt newerplatforms. The general approach of such developers is to provide toolsthat extract and convert the configured information of the existing HMIapplications from existing HMI applications into HMI applications thatwill run on the new technological platforms.

An exemplary environment within which supervisory control and dataacquisition (SCADA) and manufacturing execution system (MES) arepotentially implemented is described, for example in Krajewski III, etal., U.S. patent application Ser. No. 10/943,301 which corresponds to USApp. Pub. 2006/0056285 A1, and Krajewski et al., U.S. patent applicationSer. No. 11/549,801 which corresponds to US App. Pub. 2008/0189637 A1,the contents of which are incorporated herein by reference in theirentirety, including any references contained therein. The MES is, by wayof example, the Wonderware Operations Software (formally known asFactelligence), which provides a scalable and configurable ManufacturingExecution System (MES) designed to help manufacturers across a widerange of industries improve their operational efficiency, manufacturingresponsiveness and brand integrity, a product of Invensys, Systems, Inc.The MES differs from the SCADA component in that it is not generallyused to exert supervisory control over a plant/manufacturing process.Instead, the MES monitors production and records variousproduction/manufacturing events and applies known business rules torender decisions governing production operations carried out by theSCADA system. MES systems interface to higher level enterprise resourceplanning (ERP) systems.

SUMMARY OF THE INVENTION

In one form, a system manages human machine interface (HMI) applicationsfor industrial control and automation. Software instructions stored on atangible, non-transitory media and executable by a processor receivedata indicative of a manufacturing/process control system beingmonitored and display a user interface indicative of a status of themanufacturing/process control system being monitored wherein the statusis based on the received data.

DETAILED DESCRIPTION

The following description is based on embodiments of the invention andshould not be taken as limiting the invention with regard to alternativeembodiments that are not explicitly described herein. By way of example,the present invention is incorporated within a supervisory processcontrol and manufacturing information application development andruntime environment wherein individual data sources (e.g., processequipment and associated logic) are represented by application objects.An example of such system is described in detail in Resnick et al., U.S.patent application Ser. No. 10/179,668 filed on Jun. 24, 2002, whichcorresponds to US App. Pub. 20020198920, for SUPERVISORY PROCESS CONTROLAND MANUFACTURING INFORMATION SYSTEM APPLICATION HAVING A LAYEREDARCHITECTURE, the contents of which are incorporated herein by referencein their entirety including the contents and teachings of any referencesidentified/contained therein. However, as those skilled in the art willappreciate in view of the disclosed exemplary embodiments, the presentinvention is potentially applicable to a variety of alternativesupervisory process control and manufacturing information applicationdevelopment and runtime environments.

The disclosure herein is directed primarily to an infrastructure andrelated methods for centrally managing HMI applications (e.g., INTOUCHapplications) within a supervisory process control and manufacturinginformation application environment comprising potentially manynetworked HMI nodes running separate instances of a previously definedHMI application. The disclosure includes a description of an HMIapplication encapsulated within a reusable HMI application template.Thereafter, HMI application objects are instantiated from the HMIapplication template and installed on a designated networked HMI node.

A second aspect of centrally managing HMI applications disclosed hereinrelates to propagating changes to symbols making up a portion of thegraphics of an HMI application template into a set of HMI applicationobject templates. By way of example, a symbol template is globallydefined outside the HMI application. The symbol graphics areincorporated into HMI application templates via a reference to thecentrally managed symbol template. The use of symbol templates to definesymbol graphics for HMI applications facilitates propagating changes(using the aforementioned cross-reference lists) to the symbol templatesdown to all child symbol templates as well as all HMI applicationtemplates that incorporate by reference the changed original and derivedchild symbol templates. Such relationships and propagation paths aredescribed in US App. Pub. 2008/0189637 A1 with reference to FIG. 5, isincorporated herein by reference.

A third aspect of centrally managing HMI applications disclosed hereinrelates to maintaining and graphically presenting a status for HMIobjects in various views (e.g., deployment, derivation, model, etc.) ofthe contents of the configuration database 124 via the IDE 126. Examplesof current status include: checked in/out, deployed/undeployed, andchanged. Each of these exemplary statuses enables users to makedecisions with regard to distributing instances of an HMI application.

Yet another aspect of the disclosed central management arrangement isthe ability of users to edit an existing HMI application definition(template) from a remotely deployed configuration tool such as anIntegrated Development Environment (IDE) facility.

FIG. 1:

Referring to FIG. 1, a schematic diagram depicts hosting/hierarchicalrelationships of components within an exemplary distributed/networkedsupervisory process control environment. In the exemplary network, eachof the multiple computing hardware nodes (PCs 100, 120, 130, 132, 134)run bootstrap software that operates as the host for subsequently loadedplatform objects and a development tool referred to herein as the IDEfacility. Thereafter, platform object instances are installed on thePCs. Only one platform object can be installed on each PC. The platformobjects host and provide services to subsequently installed engineobjects. The engines objects, in turn, potentially operate as hosts tosubsequently installed HMI, device integration and application objects.The engine objects are distinguished by their differing services/hostingcapabilities—and thus the type of objects they host. For example, viewengines host HMI object instances while application engines host deviceintegration objects and application objects. The various types ofobjects mentioned above are described further herein below.

With continued reference to FIG. 1, multiple PCs 120, 130 and 134 run anintegrated design and development tool (IDE 126 a-c). The IDE 126 isutilized by developers to configure and deploy components, includingapplication objects, of a supervisory process control and manufacturinginformation system to designated PC nodes attached to an engineeringnetwork 119. The IDE 126 is a utility (comprising potentially multiplecomponents) from which process control and manufacturing informationapplications, including application objects and engines, are defined,created and deployed to a variety of platforms/engines including, forexample, the application server PC 100. Developers of a supervisoryprocess control and manufacturing information application, through theIDE 126, carry out a wide variety of application design functionsincluding: importing new object and template types, configuring newtemplates from existing templates, defining new application objects, anddeploying the application objects to the host application engines (e.g.,AppEngine1 on the application server PC 100). The IDE 126 is also whereHMI templates, incorporating previously developed HMI applications, aredefined and resulting HMI objects are instantiated and deployed totarget PCs having a previously installed view engine (e.g., view engines129 a and 129 b).

The IDE 126 copies operate upon a set of object templates stored in aconfiguration database 124 (e.g., Galaxy database) wherein the names ofthe defined object templates are maintained in a global name table 125.The global name table 125 facilitates binding location independentobject names to location-derived handles facilitating routing messagesbetween objects within the system depicted in FIG. 1. The configurationdatabase 124 stores, for a configured application component, object dataas well as any code or documents associated with the configured objects.The configuration database 124 stores both base object templates andderived templates for the various objects (e.g., application engines,application objects, view engines and HMI objects) depicted in FIG. 1.An exemplary visualization HMI application object derivation andinstance creation scheme described in US App. Pub. 2008/0189637 A1 withreference to FIG. 5, is incorporated herein by reference. In anexemplary embodiment, the configuration database 124 comprises aMICROSOFT SQL server.

The contents of the configuration database 124 are accessed via aconfiguration database engine 122, also known as a galaxy repository.The configuration database engine 122 supports remote, multi-user accessvia the IDE 126 copies through graphically presentablecheck-in/check-out status descriptors for each defined object in theconfiguration database 124. The configuration database engine 122 alsosupports deployment of objects and software from a centralized source toother nodes on the system.

In accordance with an illustrative embodiment, a data quality and statusbehavior definition 123 is stored within the configuration database 124.From this centralized location, a global data distribution mechanismautomatically delivers the new version of the definition 123 to all theruntime nodes without further user intervention. The definition 123,specifying animated graphical behaviors in response to data statuses, isshared across the entire set of nodes and HMI applications that fallwithin the scope of the configuration database 124, and is not specificto any individual node or HMI application.

In the illustrative embodiment, the configuration database engine 122 ishosted by a configuration database platform 127. The configurationdatabase platform 127 is generally the same as the other platformsinstalled on the PCs in the system. However, the configuration databaseplatform 127 is assigned a unique status (and corresponding name) withinthe system as the platform associated with the single activeconfiguration database 124. Thus, the disclosed system includes asingle, centrally managed configuration database. In alternativeembodiments, multiple copies of the contents of the database 124 aremaintained (e.g., a read-only or backup copy of the contents of thedatabase 124) on multiple nodes in the system. In the illustrativeembodiment, the configuration database platform 127 and the hostedconfiguration database engine 122 perform the specialized functions of:data/software distribution, maintaining the global name table 125,resolving (using the name table 125) globally uniquelocation-independent reference strings to location-derived handles (formessage exchange), administering security/limited access to resources ina multi-user environment, versioning, centralized license management andimporting/exporting object templates and instances.

The IDE 126 supports a variety of configuration operations involving theconfiguration database 124. By way of example, engineers utilize the IDE126 to import new object templates into the configuration database 124(via the configuration database engine 122), configure new objecttemplates, and deploy the objects to designated PCs on the engineeringnetwork 119. As noted above, multiple copies of the IDE 126 residing ondistinct network nodes are capable of accessing and editing the objectdefinitions, including HMI application definitions and symboldefinitions that are potentially incorporated into the HMI applicationdefinitions (templates).

In the illustrative example, multiple HMI object instances 128 a-b aredeployed on multiple hardware nodes (PCs 130 and 132). The HMI objectinstances 128 a-b, described in US App. Pub. 2008/0189637 A1 withreference to FIG. 4 is incorporated herein by reference, provide agraphical view/window representing a current status of a process/plantor portion thereof based upon information obtained via deviceintegration and application objects from devices/controllers residing ona plant floor network 115. A single view engine hosts multiple distinctHMI object instances corresponding to various configured process/plantviews driven by information provided by, for example a connected fielddevice or PLC (e.g., PLC 112). In the exemplary embodiment, the HMIobject instances 128 a-b are hosted by view engines 129 a-b (describedin US App. Pub. 2008/0189637 A1 with reference to FIG. 3, incorporatedherein by reference) in a multi-layered supervisory process control andmanufacturing information system architecture. While only a single HMIobject instance is shown for each view engine in FIG. 1, each viewengine is capable of simultaneously hosting multiple HMI objectinstances.

The hosted relationship between HMI object instances 128 andcorresponding view engines 129 facilitate access to certain servicessupported by the view engines 129. By way of example the view engines129 support updating the hosted HMI object instances 128 independently(automatic change propagation when corresponding templates are updated).Also, the view engines 129 cache (on the associated network node) thedisplays associated with the HMI object instances 128.

Turning to the application server1 PC 100 on the engineering network119, in the illustrative embodiment, data sources are presented, by wayof example, in the form of application objects 105. The applicationobjects 105 carry out a variety of functions including, representing thestatus of process equipment and associated application logic. Theapplication objects carry out any of a variety of monitoring/controlfunctions while positioned at an application level of the illustrateddistributed hierarchical supervisory process control and manufacturingapplication architecture. Device integration objects 106 a and 106 b,situated at an application level as well in the hierarchy, representdata sources on a plant floor network such as PLCs (PLC1), smart fielddevices, and associated I/O networks (e.g., PLC1 network).

The application objects and device integration objects communicate withone another both locally (within a single personal computer) and throughnon-local communications with objects hosted on personal computersattached to the engineering network 119.

The application objects 105 are identified, by way of example, withinthe global name table 125 maintained by the configuration database 124(e.g., the WONDERWARE Galaxy Repository)—the contents of which are madeavailable to a developer via, for example the IDE 126 a-c and HMI objectinstances 128 a-b that, by way of example, incorporate INTOUCHapplications and their associated displays. Thus, in accordance with anembodiment of the present invention, a dynamic graphical view of aplant/process in the form of an INTOUCH application is initially createdusing, for example, the WINDOWMAKER utility. The entire INTOUCHapplication is thereafter incorporated into an HMI object templateincluding necessary components for use in the multi-leveled applicationexecution environment described herein. The resulting HMI objecttemplate is stored/maintained/managed in the configuration database 124.Thereafter, subsequent derived versions of the base template aremaintained as children, and retain an inheritance relation, with theparent HMI object template. The original and derived templates areavailable for distribution via the IDE 126 to appropriate nodes on thenetwork 119 containing a previously installed view engine (e.g. viewengine 129 a).

With continued reference to FIG. 1, the application server 1 PC 100executes a multi-layered supervisory process control and manufacturinginformation application comprising a first portion 104. The applicationportion 104 includes the application objects 105 and device integrationobjects PLC1Network 106 a and PLC1 106 b. The PLC1Network 106 a deviceintegration object facilitates configuring a data access server (e.g.,OPC DAServer 116). The PLC1 106 b device integration object, operatingas an OPC client, accesses data locations within the buffers of the OPCDAServer 116. The data access server 116 and the device integrationobjects cooperatively import and buffer data from external processcontrol components such as PLCs (e.g., PLC1 112) or other field devices(not depicted) on the plant floor network 115. An application engine 107hosts both the application objects 105 and device integration objects106 a and 106 b. The application engine 107, as a host, managesperiodic/event driven execution of the hosted application anddevice-integration objects. The aforementioned components of thehierarchical hosting arrangement on the PC 100 described in US App. Pub.2008/0189637 A1 with reference to FIG. 2 is incorporated herein byreference.

In the illustrative example, requests for data are submitted via thedata access server 116 to retrieve data from the PLC1 112. The retrieveddata is thereafter used by the HMI object instances 128 a and 128 b todrive graphical displays representing, for example, the status of plantfloor equipment. The data buffer of the data access server 116 isaccessed (directly/indirectly) by the variety of application-levelobjects (e.g., application objects 105, PLC1Network 106 a, PLC1 106 b,etc.) executing upon the personal computer 100. Examples of applicationobjects represent data sources and logic including, by way of example,discrete devices, analog devices, field references, events/triggers,production events, etc. In an exemplary embodiment, informationobtained/provided by the application-level objects 105, 106 a and 106 bis stored in a runtime (Historian) process information database (notshown). The data is thereafter obtained by the HMI object instances 128a-b to drive a display state of animated process graphics.

The data access server 116 is, by way of example, an OPC Server.However, those skilled in the art will readily appreciate the widevariety of custom and standardized data formats/protocols that arepotentially carried out by the data access server 116. Furthermore, theexemplary application-level device integration objects 106 a and 106 b,through connections to the data access server 116, represent a PLCnetwork and the operation of the PLC itself. However, theapplication-level objects (e.g., device integration and applicationobjects) hosted by the application engine 107 comprise a virtuallylimitless spectrum of classes of executable objects that perform desiredsupervisory control and data acquisition/integration functions in thecontext of the supervisory process control and manufacturing informationapplication.

The supervisory process control and manufacturing information system ispotentially integrated with a variety of processes/plant informationsources via a variety of communication channels. The exemplary systemincluding the multi-layered application comprising portion 104 iscommunicatively coupled to the PLC1 112. The PLC 1, in turn, receivesplant equipment status information via the plant floor network 115. In aparticular embodiment, the PLC 112 comprises a node on an Ethernet LANto which the PC 100 is connected. In other embodiments, the PLC 112 islinked directly to physical communication ports on the PC 100. In stillother alternative embodiments the PC 100 receives data from field I/Omodules that receive, for example, analog data from field devices thatoperate in a distributed regulatory control system.

Thus, as illustrated in FIG. 1, a system for managing human machineinterface (HMI) applications for industrial control and automation isprovided The system comprises a processor such as PC 100 in combinationwith software instructions stored on a tangible, non-transitory mediaand executable by the processor. The instructions comprise instructionsfor receiving data indicative of a manufacturing/process control systembeing monitored (e.g., data stored in database 124) and instructions fordisplaying a user interface indicative of a status of themanufacturing/process control system being monitored (e.g., applicationobjects 105) wherein the status is based on the received data.

It is noted that the system depicted in FIG. 1 and described hereinaboveis merely an example of a system including a multi-layered hierarchicalarchitecture for a supervisory process control and manufacturinginformation system. It is further noted that FIG. 1 is presented as alogical view of the hosting and/or containment interrelations betweeninstalled components including software and physical computing hardware.The system disclosed herein is suitable for virtually any networktopology. For example, the present invention is applicable to a systemwherein both configuration utility and supervisory process controlvisualization applications run on a single computer system linked to acontrolled process.

Alarms and Events

An alarm is an event that has a state and requires operatorintervention. It requires an acknowledgement. Alarms are detected bysoftware components and reported using alarm distribution mechanisms tobe discussed later. Every alarm is reported, or sent, using a datastructure that contains data fields that define the information for thealarms. The following list contains fields sent with an alarmnotification. The alarm primitive which generates this message needs tosupport generation of these fields, but may also have other attributes.Fields that are historized to event history are marked “Historized”.

-   -   TagName—tag generating alarm, e.g. “TIC101” (Historized)    -   Name—name of alarm, e.g., “PV.HiAlarm” (Historized)    -   InAlarm—indication of whether the condition is currently active        or inactive. (Boolean).        -   (Historized)    -   Quality—current data quality of the data upon which the alarm is        based. (MxQuality) (Historized)    -   OnTimeStamp—the time the condition went into alarm. (Time)        (Historized . . . when goes into alarm):    -   Alarm On timestamp [AppServer Callisto] this should be the        timestamp of the associated attribute, if available; otherwise,        it should be the AppEngine scan time    -   OffTimeStamp—the time the condition returned to normal. (Time)        (Historized . . . when goes out of alarm):    -   Alarm Off timestamp [AppServer Callisto] this should be the        timestamp of the associated attribute, if available; otherwise,        it should be the AppEngine scan time. If an active alarm is        disabled (which forces a return to normal), the timestamp should        be the Current time    -   Category—the alarm/event category, values from 1-14 set by        Wonderware. These values are to be associated with        Internationalized Category labels set by Wonderware as follows.        (Historized)

TABLE 1 CATEGORIES Category Category Label Ordinal (English) Meaning(only documented, not in system) 1 Discrete A discrete value event oralarm, such as a change of state. 2 Value A continuous value issignificantly below LoLo acceptable range. 3 Value Lo A continuous valueis below or approaching below acceptable range. 4 Value Hi A continuousvalue is above or approaching above acceptable range. 5 Value Acontinuous value is significantly above HiHi acceptable range. 6Deviation A value has a minor deviation (+/−) from target Minor orsetpoint. 7 Deviation A value has a major deviation (+/−) from targetMajor or setpoint. 8 ROC Lo A value's rate of change is slower thanacceptable. 9 ROC Hi A value's rate of change is faster than acceptable.10 SPC A value deviates from the SPC target/range. 11 Process An alarmor event associated with the physical process/plant has occurred. 12System An alarm or event associated with the automation system hasoccurred. 13 Batch An alarm or event associated with a batch process hasoccurred. 14 Software An alarm or event associated with a softwareoperation/logic (such as divide by zero in script) has occurred.

Referring to TABLE 1, above, the category labels are retrieved from adictionary file by the UI clients and by the INTOUCH alarm provider,since it requires these strings. These strings can be localized to otherlanguages. The INTOUCH provider is to use the default galaxy language toretrieve these strings and send them to INTOUCH. Thus, they will onlyappear in INTOUCH and INTOUCH history as the default galaxy languagestrings. The future view engine will use the locale of the client,meaning only the category ordinal is to be historized. (Historized).

-   -   Priority—an integer value from 0-999 indicating the urgency of        the alarm. By default, Zero is most urgent, 999 is least urgent        (as in INTOUCH). This is the opposite of OPC. Since INTOUCH does        not support 0, 0 is converted to 1 prior to sending to INTOUCH        provider API. In the ArchestrA Apollo Project this is a        configurable option with mapping of priority ranges to severity        levels. (Historized)    -   TargetValueReference—(optional field)—reference to target value        for the condition (MxReference). (not Historized)    -   ActualValueReference—(optional field)—reference to the actual        value for the condition (MxReference). (not Historized)    -   TargetValue Snapshot—(optional field)—target value for the        condition at time of alarm.        -   (Historized)    -   ActualValueSnapshot—(optional field)—actual value for the        condition at time of alarm (Historized)    -   EngUnitsReference—(optional field)—reference to the engineering        units string for the condition (MxReference). (Historized)    -   AcknowledgedFlag—indicates whether alarm has been acknowledged        yet. If this flag is false, the alarm is waiting for an        acknowledgment. (Boolean) (Historized as event)    -   AcknowledgeTime—indicates time alarm was acknowledged if        AcknowledgedFlag is true. (Time) (Historized . . . when gets        acknowledged)    -   AcknowledgeUserId—String containing name of user who        acknowledged alarm, if currently active and acknowledged.        (Historized . . . when gets acknowledged)    -   AlarmMode—indicates whether alarm is Enabled, Silenced or        Disabled. (enum).        -   (Historized . . . when changes state).    -   Message—Message text describing the alarm. Can be either        statically configured or dynamically constructed. Typically        contains alarm description, possibly the limit value exceeded,        and possibly the variable value. For the standard alarm utility        primitive, this message is retrieved via a reference to a        string/international string attribute in the object. The        reference is setup at ObjectDesigner time for standard alarm        primitives. If none is specified, then the common primitive        short description attribute is utilized. This field is also        provided in the alarm extension primitive and can be dynamically        generated and scripted. The alarm extension primitive is in        Slice 07. (Historized)    -   Area—area for the object (Historized)

On a global (per galaxy) basis, the user of the IDE (IntegratedDevelopment Environment of Archestra) can edit the galaxy object toconfigure the mapping of alarm priority to severity and its associatedsettings.

FIG. 18 illustrates one example of a screen shot 2202 of a userinterface for configuring alarm and priority mapping. Settings for thepriority to severity mapping as shown in FIG. 18 are as follows:Description, Historize, From Priority Range, and To Priority Range,settings for each Severity. (Note: Severity 1 must start at 1. Severity4 must end at 999.) FIG. 19 illustrates one example of a screen shot2302 of a user interface for configuring alarm element styles mapped forseverity, mode, acknowledged state.

Thus, the user is given the actual flexibility in changing what thesebands actually mean. So, a particular project might define theseSeverities to be reversed from the defaults provided by Wonderware ifthey were interested in OPC compatibility more than INTOUCHcompatibility. The Alarm Summary Display is configurable to sort from 1to 999 or from 999-1 on Priority. By default, it shows priority 1 alarmsat top and 999 alarms at bottom (the INTOUCH default). For example, allnon-bold items in TABLE 2 below can be edited in the Galaxy object.

TABLE 2 Default Alarm Priority Severities in Galaxy Object From PriorityTo Priority Severity Description Historize Range Range 1 Critical Y 1250 2 High Y 251 500 3 Medium Y 501 750 4 Low Y 751 999In addition, Events can be configured into groupings as shown in TABLE 3below:

TABLE 3 Default Event Priorities in Galaxy Object Types DescriptionHistorize 1 System Y 2 Application Y 3 User NRetrieval of Priority Mapping for Use by AppServer Components:

The mapping information is stored in a file named Data5.txt in theGlobal Data Cache and is automatically distributed from the GR to allplatforms in the Galaxy.

-   -   On each platform, this information is retrieved by the Alarms &        Events subsystem and is made available to all Alarms & Events        components that need to deal with Severity.    -   The mapping information is retrieved at start-up. It is also        retrieved at runtime whenever the file Data5.txt is updated.        Runtime updates are accomplished via the Global Data Cache        subscription mechanism so the file is re-read ONLY when it is        updated.    -   A simple call to a singleton component's method        GetSeverityForPriority( ) is all that is necessary for        retrieving the Severity for a corresponding Priority, for any        AppServer component on an Engine.        -   If this function returns zero, it means a corresponding            Severity could not be found for the indicated Priority. In            this case, it is up to the caller to declare an error            situation or substitute a meaningful default value.

Note: In a multi-Galaxy environment in which Galaxies are not sharingGlobal Data Cache information, it is possible that one Galaxy may have adifferent Priority to Severity mapping than another. For example, ifGalaxy1 has alarms with Priorities 1-300 mapped to Severity 1 andGalaxy2 has alarms with Priority 1-200 mapped to Severity 1, then analarm with Priority 250 will be mapped to Severity 1 on Galaxy1 andSeverity 2 on Galaxy2.

The ITAlarmProvider reports Severity to the INTOUCH Distributed AlarmSystem (AlarmMgr) in the User1 data field. This field can be displayedon all INTOUCH alarm displays and on the ArchestrA Alarm Client (EAC).The display client can be configured to label the column header as“Severity”.

To ensure that Alarmed attributes will always have current data, thealarm primitive and the alarm extension primitive register a referenceto the alarmed attribute. This will guarantee that message exchange willnever suspend updates for this attribute. Even if alarms are disabledfor a particular attribute, the Scan On Demand feature will not befunctional (i.e. the attribute cannot be Suspended).

This section describes the system components that detect an alarm orevent and also report that alarm or event. Alarms and events can bedetected by software components in the system. Events can be reported bya larger variety of components than alarms. Events can be detected byvirtually any component in the system, including AutomationObjects, SMC,etc. Events are thus more general purpose than alarms and provide ameans for any software component to indicate a condition or occurrenceof interest to the event system. For example, the SMC can report a userlog-in message as an event (>R0.5). Several types of events can bereported as described earlier. When any component reports an event, ituses an event API to do so. The component implementing the event APIreports its event messages to Alarm/Event distributors and History,described later in this document. Events are sent to INTOUCH forreal-time display and for historization.

Alarms can only be detected by AutomationObjects. Any AutomationObject(including Platforms, Engines) can detect and generate an alarm. Todetect an alarm, the AutomationObject must provide detection logic andset a Boolean Attribute flag to indicate whether the alarm is currentlyactive or inactive.

If the alarm is associated with an attribute that supports buffereddata, the AutomationObject's detection logic must set the Bufferproperty of the Boolean condition Attribute with a VTQ array (V being aBoolean representing whether or not the condition is true or false).There should be one VTQ for every VTQ in the base attribute's buffer, sothat when the alarm messages are composed, PV can be extracted from thebase attribute's buffer. Times for the corresponding elements in thebase attribute's buffer and resulting Boolean condition attribute'sbuffer should match. Sequence of alarm state changes can be generated asa result of processing the condition buffer. A set of alarm messagescorresponding to the alarm state changes will be composed and sent tothe Notification Distributor.

The user can only acknowledge the current alarm. Alarm monitoringbuffered attribute can be enabled/silenced/disabled/inhibited. To reportan alarm, the AutomationObject must contain an Alarm Primitive. TheAlarm Primitive examines the Boolean condition to determine whether thealarm is active. An Alarm Primitive is dedicated to reporting a singlealarm condition's state. Alarm Primitives report their alarm messages toAlarm/Event distributors, described later in this document.

This section describes the impact of data quality on alarm reporting.Alarms are only reported when the data quality of the (true) Booleancondition flag is either Good or Uncertain.

Alarms are only cleared when the data quality of the (false) Booleancondition flag is either Good or Uncertain.

If the condition flag is Bad or Initializing quality, the state of thecondition flag is ignored and no new alarm reports or alarm clearsoccur. As an example, assume the following occurs during normalexecution of an object:

-   -   An alarm condition is true with good quality (an alarm exists).    -   The quality of the alarm condition goes bad. (the alarm is not        cleared . . . it still exists as in alarm).    -   The quality of the alarm condition goes Good (no action taken,        since the alarm already exists).    -   The quality of the condition flag does not impact alarm        acknowledgment handling at all. In other words, an alarm can be        acknowledged even if the condition flag for the alarm has bad        quality.    -   The quality of the condition flag does not impact alarm        enable/disable/silence behavior at all.

Some Objects and ArchestrA Graphics symbols—such as those in theSituational Awareness Library (SAL)—need an efficient and simple way toidentify whether any alarms on an Object currently need attention, whatis the overall status of the most important of those alarms, and howmany alarms are presently active overall at each level of severity. Inaddition, they need Alarm Aggregation (described below) to summarize allcontained Objects, following the Model View—so that the alarminformation represents the Object and all levels below it. This makes itpossible for a user to “drill down” from one level to the next and useaggregation to search for the underlying cause of a complex Object'salarms.

-   -   For an Object, aggregation represents the alarms on the Object,        on all contained Objects, and on their descendants, down to the        lowest levels of the Model View.    -   For an Area or pseudo-Area, aggregation represents the alarms on        the Area Object itself, on all Objects assigned to the Area, and        on all sub-Areas and their assigned Objects, down to the lowest        levels of the Model View.    -   For an Attribute, aggregation represents all the alarms on the        Attribute itself. This is the lowest level of aggregation.        Alarm Border Animation

As illustrated in FIGS. 1, 2, and 6, and as illustrated in the alarmborder animation support (FIGS. 18-19), a system of the inventionmanages human machine interface (HMI) applications for industrialcontrol and automation. Software instructions stored on a tangible,non-transitory media and executable by a processor receive dataindicative of a manufacturing/process control system being monitored anddisplay a user interface indicative of a status of themanufacturing/process control system being monitored wherein the statusis based on the received data. In addition, the instructions displaygraphic elements as part of the user interface. Each element isassociated with and indicative of an alarm status of one or more aspectsof the manufacturing/process control system being monitored. The alarmstatus of each graphic element is a function of the status of itsassociated plurality of alarms. The instructions are also responsive touser input for configuring a selected graphic element with a border. Theborder is selectively animated in response to the alarm statusassociated with the selected graphic element being in an alertcondition. The animation indicates that the one or more aspects of themanufacturing/process control system associated with the selectedgraphic element is not at an acceptable value. The software instructionsstored on a tangible, non-transitory media are executable by aprocessor. A processor executable method is provided.

Alarm border animation comprises processor executable softwareinstructions stored on a tangible, non-transitory media (e.g., a memorydevice) and executed by a processor/server by which a user can easilyand quickly configure any graphic element (e.g., object) or group ofelements to automatically visualize the alarming state of an entitywithin their platform application space. The user is provided with auser-selectable border from a border library for a graphic object orgroup of elements such as illustrated in FIG. 6, which automaticallyconforms to surround any object's shape, configures itself to theconnections surrounding the object, and responds to the object's alarminformation. A graphic element in the system can be configured with thisborder, which is capable of changing state (e.g., animating by blinkingor flashing) when certain conditions are met, such as when any objectwithin the border has an alarm.

FIG. 6 is a screen shot of an interface for specifying border animationillustrating examples of alarm borders and indications. Referencecharacter 602 illustrates a blinking dark gray border having a very high(HH) indication 604. Reference character 606 illustrates a blinkinglight gray border having a very low (LL) indication 608. Referencecharacter 610 illustrates a black border having a high (HI) indication612. Reference character 614 illustrates a blinking white (ortransparent) border having multiple indications 616 superimposed on eachother. Reference character 618 illustrates a patterned border having alow (LO) indication 620.

In the past, if a user wanted to put a border around something thatwould flash red, there were a series of things the user needed to do. Ittook a while to craft that graphic element and then hook it up to theright thing. The alarm border animation software instructions create a“native animation” that can be attached to all the graphic objects.Using this native animation, the alarm border animation softwareinstructions can make the border of any graphic object blink based oncertain stuff. For instance, if the object has the most severe alarm,the border of it will blink red. The border itself will conform to anyirregular shape that it has taken on. Also, based on the invention, anobject can have a blinking border when any object within it has a highseverity alarm. Thus, the processor executes instructions for specifyinga user-defined level of hierarchy for the plurality of alarms of eachelement, instructions for specifying a user-defined hierarchy level foreach element above which an alarm is considered severe, instructions forexposing a severe alarm above the user-defined hierarchy level, andinstructions for exposing a severe alarm of a particular element whenany sub-element within the particular element has a severe alarm.

The border will be automatically drawn around whatever shape the userconnects it to. It is not a separate element that the user has to draw.It is a new facet of every graphic element in the system automatically.The most powerful part is that it automatically configures theconnection and automatically consumes alarm aggregation data from theapplication server providing the data from the manufacturing/processcontrol system being monitored by the MES.

One reason this is so important, is because of the time savings to ourusers and the reduction of error rate in configuration of a system.

In the Wonderware Application Server, the user's application is dividedup into software entities called Objects.

-   -   Objects exist in a hierarchy where Objects can contain other        Objects.    -   Each Object can have zero or more alarms configured on it, each        with a different level of severity.    -   Alarm Aggregation provides a summary of the alarms at each level        in the hierarchy tree to help the user quickly identify which        Object has the most urgent alarms in the overall system, and        even in which specific part of the Object.

This enables the user to prioritize which alarms to address first, andto quickly locate where the corrections need to be made.

This new animation is introduced in ArchestrA and INTOUCH graphics thatallows user to visualize the state of the alarm. The user is able toconfigure the alarm border animation on any graphic element. Theanimation can point to the alarm aggregated attributes and it willrender the border and indicator base on the alarm states. Thus, theprocessor executes instructions responsive to a user for configuring theanimation of an element to point to an aggregated alarm attribute.

Objects, Areas, and Alarms:

In the Wonderware Application Server (also known as “AppServer”) theuser's application is divided up into software entities called Objects.Objects can be arranged in a hierarchy where (1) some Objects cancontain other Objects, (2) Objects can be grouped into Areas, each ofwhich contains many Objects, and (3) an Area can also contain sub-Areas.

Each Object can have zero or more alarms configured on it, each with adifferent level of severity.

Areas are a special kind of Object that can contain multiple Objects andother Areas. One of the purposes for an Area is to collect and cache allthe information about the current alarms for all the Objects andsub-Areas that it contains.

Application Objects (also known as AppObjects) are a specific kind ofObject that can contain data in the form of Field Attributes. FieldAttributes have a number of different behaviors that can be configured.An individual Analog Field Attribute can have several different alarmsconfigured on it, each with a different level of severity. So evenwithin a single AppObject, there might be multiple Field Attributes,each with its own most urgent alarm.

The collection of AppObjects and Areas form a hierarchy tree, which iscalled the “Model View.” Each AppObject has one “parent.” This parentmay an Area, or it may be another AppObject. But every AppObject musthave a parent. An Area, however, can only be the child of another Area,or it may have no parent at all.

Alarm States

Each individual alarm is handled by an Alarm Primitive. An alarm hasmultiple states and the processor executes instructions for selectivelyrendering a particular style of border or a particular type of animationfor each state of an alarm.

-   -   The Alarm Primitive monitors a Boolean condition Attribute, and        when that attribute changes state the Alarm Primitive reports        the alarm has become active (InAlarm) or has returned to normal.    -   The Alarm Primitive also has a state. When an alarm occurs, two        things must take place for the alarm to be considered fully        addressed: (1) it must be acknowledged by an operator, (2) it        must be returned to normal (usually by fixing the problem).        These can happen in either order, but BOTH must take place for        the alarm to return to its “resting” state.    -   The Alarm Primitive also has a mode of operation. In the Enabled        mode, the alarm is fully functional. In the Silenced mode,        changes to the alarm state are recorded in the alarm history        database, but they are NOT annunciated or displayed on the        operators' display screens. In the Disabled mode, the alarm is        always held in the “Off” state, regardless of the status of the        Boolean condition attribute.

Each Alarm Primitive has two important flags:

-   -   InAlarm: TRUE when alarm is in the active “in alarm” state    -   Acked: TRUE when the alarm has been acknowledged

The conditions of these flags define the four basic STATES for an alarm,as seen in TABLE 4 below:

TABLE 4 States of an Alarm InAlarm = FALSE InAlarm = TRUE Acked = FALSEUNACK_RTN UNACK_ALM Acked = TRUE ACK_RTN ACK_ALM

-   -   ACK_RTN 202: This is the “ground state” for alarms. Not in        alarm, not waiting for an acknowledgment. It is NOT displayed on        the Summary List (Current Alarms).    -   UNACK_ALM 204: This is the state the alarm border animation        software instructions goes to when an alarm is first raised. It        is active and waiting for an ACK. It shows up on the Summary        List (Current Alarms).    -   ACK_ALM 206: If the alarm is ACKed (acknowledged) but has not        yet returned to normal, it still shows up on the Summary List        (Current Alarms).    -   UNACK_RTN 208: If the alarm returns to normal without being        ACKed, it still shows up on the Summary List (Current Alarms).

These states are shown in INTOUCH in the alarm displays (ActiveX AlarmViewer, Alarm DB Viewer, and ArchestrA Embedded Alarm Client). The“Current Alarms” display shows only UNACK_ALM, ACK_ALM, and UNACK_RTN.These are the alarm states that need attention. They need somebody to DOsomething: either fix the problem, acknowledge the alarm, or both.

Drawn as a state diagram, these states and transitions are illustratedin FIG. 2. When an alarm becomes active from normal, the systemtransitions from state 202 to state 204 as illustrated by arrow 210. Atstate 204, if the operator acknowledges the alarm, the systemtransitions to state 206 as illustrated by arrow 212. At state 206, thesystem transitions to state 202 as illustrated by arrow 214 when thealarm returns to normal. At state 204, if the alarm returns to normalbefore being acknowledged, the system transitions to state 208 asillustrated by arrow 216. At state 208, the system transitions to state202 as illustrated by arrow 218 after the operator acknowledges thealarm.

Each Alarm can be ENABLED, SILENCED, or DISABLED. The meanings are asfollows:

-   -   Enabled: Alarm is fully functional. When the condition becomes        TRUE the alarm state becomes active and everybody can see it on        the INTOUCH display screen.    -   Silenced: Alarm is fully functional. When the condition becomes        TRUE the alarm state becomes active. However, it does not get        displayed on the screen. It is recorded in the Alarm Database.        (In other words, this is a Historization-only setting.)    -   Disabled: Alarm is forced OFF. Even when the condition becomes        TRUE, the alarm state remains FORCED to the ACK_RTN state. It is        never waiting for an acknowledgement.

The Enable/Silence/Disable setting can be done at the Area level, Objectlevel, and individual Alarm level.

In summary, to monitor the alarm state(s) of a graphic element, a usercan configure an alarm border animation on the graphic element. The usercan configure the animation to point to any aggregated alarm attributes.The animation will render the border around the graphic element. Adifferent style of border can be rendered for each state of the alarm.These styles are defined in the Galaxy Style Library. Instructionsexecuted by a processor of the system display graphic elements as partof the user interface so that each element is associated with andindicative of an alarm status of one or more aspects of themanufacturing/process control system being monitored. Instructionsexecuted by a processor of the system are responsive to user input forconfiguring a selected graphic element with a border which isselectively animated in response to the alarm status associated with theselected graphic element being in an alert condition indicating that theone or more aspects of the manufacturing/process control systemassociated with the selected graphic element is not at an acceptablevalue. In various embodiments, these instructions may be part of asystem, and/or may be part of software instructions stored on atangible, non-transitory media and executable by a processor, and/or maybe a processor executable method.

The aspects of this feature are at least two-fold: The first is the wayin which the system eliminates the need for tedious and error-prone,repetitive data entry tasks which normally need to be done by the userin order to realize this same level of functionality. And secondly,without any additional input from the user the alarm border will drawitself around the element to which it is applied, regardless of theshape/size of the element.

FIG. 6 is a screen shot of an interface for specifying border animationillustrating examples of alarm borders and indications. An alarm borderanimation user interface is illustrated in the alarm border animationsupport (FIGS. 6, 18-19).

Besides rendering the border, the alarm border animation is alsorendered an indicator on the left corner of the graphic element if userenables this functionality when configuring the animation. The defaultimage of the indicators can be changed launching the Alarm PriorityMapping configuration dialog. When changing the indicators in the galaxyit will be propagated to runtime nodes without having to redeploy theapplication. The indicators may be indicative of a parameter associatedwith an alarm, such as a hierarchy or level. Thus, the processorexecutes instructions for selectively rendering in response to a userselection an indicator on or adjacent the graphic element wherein theindicator is indicative of a parameter associated with the alarm.

Alarm Aggregation

As illustrated in FIGS. 1 and 7, a system manages human machineinterface (HMI) applications for industrial control and automation.Software instructions stored on a tangible, non-transitory media andexecutable by a processor receive data indicative of amanufacturing/process control system being monitored and display a userinterface indicative of a status of the manufacturing/process controlsystem being monitored wherein the status is based on the received data.In addition, instructions display graphic elements as part of the userinterface. Each graphic element is associated with and indicative of astatus of a plurality of alarms of aspects of the manufacturing/processcontrol system being monitored. The alarm status of each graphic elementis a function of and based on the status of its associated plurality ofalarms. In various embodiments, these instructions may be part of asystem, and/or may be part of software instructions stored on atangible, non-transitory media and executable by a processor, and/or maybe a processor executable method.

Alarm aggregation collects and exposes, via standard attributeinterface, a summary of the aggregate alarming states of an element inthe physical equipment hierarchy, including that of all elements belowit in the hierarchy. Alarm aggregation comprises processor executablesoftware instructions stored on a tangible, non-transitory media (e.g.,a memory device) and executed by a processor/server providing for agraphical object representing physical equipment organized within ahierarchy. The system collects and organizes alarms in a hierarchy. Itexposes a severe alarm above a user-defined level of hierarchy after theaggregated alarming state of the object is determined. Thisdetermination involves all sub-objects below that object in thehierarchy reporting their alarm state severity (which is determined inpart by whether the alarm has been suppressed) “from the bottom up,”instead of analyzing the entire hierarchy “from the top down” as wasdone in the prior art. Thus, the element may be an object and theprocessor executes instructions for determining sub-objects below theobject in the hierarchy reporting their alarm state severity from thebottom up instead of analyzing the entire hierarchy from the top down.

Sorting Precedence for Alarm Aggregation:

For Alarm Aggregation, identification of the “most urgent” alarm(s) usesthe following sorting precedence:

-   -   AlarmMode: Enabled precedes Silenced        -   InAlarm: TRUE precedes FALSE            -   Acked: FALSE precedes TRUE                -   Severity Level: 1 is most important, 4 is least                    important    -   The alarm border animation software instructions only aggregate        alarms in the UNACK_ALM, ACK_ALM, and UNACK_RTN states. (ACK_RTN        alarms do not need attention.)

An alarm that is Disabled cannot go into the InAlarm state, so there isnothing to aggregate.

For example, given the following three alarms, the order of urgency isas follows: UNACK_ALM with Severity 3>ACK_ALM with Severity 2>UNACK_RTNwith Severity 1.

The “most urgent” alarm on an Object is the one at the top of thesorting order as described above. If two or more alarms on an Objecthave the same “most-urgent” combination of AlarmMode, InAlarm status,Acked status, and Severity, they have the same ranking for AlarmAggregation.

In the Wonderware Application Server, the user's application is dividedup into software entities called Objects.

-   -   Objects exist in a hierarchy where Objects can contain other        Objects.    -   Each Object can have zero or more alarms configured on it, each        with a different level of severity.    -   Alarm Aggregation provides a summary of the alarms at each level        in the hierarchy tree to help the user quickly identify which        Object has the most urgent alarms in the overall system, and        even in which specific part of the Object.

This enables the user to prioritize which alarms to address first, andto quickly locate where the corrections need to be made.

A new animation is introduced in the ArchestrA graphic that allows userto visualize the state of the alarm. User is able to configure the alarmborder animation on any graphic element. The animation can point to thealarm aggregated attributes and it will render the border and indicatorbase on the alarm states.

Aggregation of Alarms for an Object:

To support alarm aggregation on Objects, each Object has a set ofAttributes that summarize the overall status of all alarms on the Objectand its descendants. These are as follows:

-   -   InAlarm—Flag indicating whether any alarms on the individual        Object are currently in the InAlarm state. [Data type:        MxBoolean]    -   AlarmMostUrgentSeverity—Severity 1-4 of the “most urgent”        alarm(s) on this Object and its descendants. If no alarms are in        the InAlarm state or waiting to be Acked, the value is 0. [Data        type MxInteger]    -   AlarmMostUrgentMode—AlarmMode of the “most urgent” alarm(s) on        this Object and its descendants. If no alarms are in the InAlarm        state or waiting to be Acked, the value is the same as the        AlarmMode for this Object. [Data type: MxCustomEnum of type        _AlarmModeEnum]    -   AlarmMostUrgentInAlarm—Flag indicating whether the alarm is        presently in the alarm state, for the “most urgent” alarm(s) on        this Object and its descendants. If no alarms are in the InAlarm        state or waiting to be Acked, the value is FALSE. [Data type:        MxBoolean]    -   AlarmMostUrgentAcked—Flag indicating whether the alarm has been        acknowledged for the “most urgent” alarm(s) on this Object and        its descendants. If no alarms are in the InAlarm state or        waiting to be Acked, the value is TRUE. (That is, no        acknowledgment is needed.) [Data type: MxBoolean]    -   AlarmCntsBySeverity—Array of counts of all alarms that are        InAlarm or waiting to be Acked on the Object and its        descendants, separated by Severity. Element 1 contains the count        of alarms of Severity 1, element 2 contains the count of alarms        of Severity 2, and so on. Note these are counts of all alarms in        the UNACK_ALM, ACK_ALM, and UNACK_RTN states. [Data type:        MxInteger array dimension 4]

These Attributes are kept up-to-date at all times on each Object duringruntime, and are updated every Scan Cycle. These Attributes are updatedevery Scan Cycle to represent the current statuses of the alarms. Atleast one of the attributes are kept up-to-date on each object duringruntime and the attributes are updated every scan cycle to represent thecurrent statuses of the alarms. Update is done in two phases:

-   -   During the execution phase, the aggregation statuses are updated        for alarms on the Object itself. These updates are done in the        ordinary execution order for Objects in an Area.    -   During the post-execution phase, the Scheduler invokes an        operation on each Object in an Area starting at the lowest        levels of the Model View hierarchy and working upward. Each        Object ensures that its own aggregation values are updated and        then performs a “bubble up” operation of those values to its        parent, which combines the parent aggregation values with those        of the child.        -   This “bubble-up” operation takes place regardless of whether            the Object is OnScan or OffScan.        -   If a child Object discovers that its parent Object is            undeployed, it skips up to the grandparent Object and            updates it. This skipping goes as many levels as needed            until an ancestor is found that is deployed or the Area is            reached, whichever comes first.        -   Note that the legacy InAlarm flag for the Object is not            “bubbled-up.” Only the new alarm aggregation attributes are            “bubbled-up.”    -   FIG. 7 illustrates one example of a hierarchy for bubble up of        Alarm Aggregation Objects. For example, object 1A_1B 702 is a        subobject of object 1A_1 704 which is part of area 1A 706 which        is part of area 1 708. Thus, mode enable, inalarm TRUE, acked        TRUE, severity 3 of object 702 bubbles up to object 704 and so        on. Similarly, the other objects bubble up as illustrated in        FIG. 7.

If there are no alarms configured on an Object or its descendants, theseattributes have the following default values:

-   -   InAlarm=FALSE    -   AlarmMostUrgentSeverity=0    -   AlarmMostUrgentMode=AlarmMode of the object itself (the Common        Primitive's Alarm State, Enabled/Silenced/Disabled)    -   AlarmMostUrgentInAlarm=FALSE;    -   AlarmMostUrgentAcked=TRUE    -   AlarmCntsBySeverity={0, 0, 0, 0}

Note: If there are no alarms configured on an Object or its descendants,then there are no Alarm Primitives executing to copy the Object'sAlarmMode status to the AlarmMostUrgentMode attribute. However, thepost-execute “bubble-up” operation executes on all Objects, whether theyhave alarms or not, whether they are OnScan or not, and makes sureAlarmMostUrgentMode is properly initialized every Scan Cycle.

Scan State and Data Quality of Alarm Aggregation Attributes:

Since alarms only update when an Object is OnScan, if an Object isOffScan, its own alarms will not contribute to the update of theaggregation values. However, in the Model View hierarchy an Object andits descendants may be in different scan states, so the statuses anddata quality need to reflect this appropriately.

If an Object is OffScan, the status of the InAlarm flag is as follows:

-   -   InAlarm=False, Good quality

[Note: The InAlarm flag always retains Good quality. This is a legacyflag that was in place for 10 years prior to the addition of the AlarmAggregation feature. So to avoid breaking existing user applications,the behavior of this flag's quality remains unchanged.]

If an Object with no descendants is OffScan, the alarm aggregationstatuses of the Object are the default values with Bad quality asfollows:

-   -   AlarmMostUrgentSeverity=0, Bad quality    -   AlarmMostUrgentMode=AlarmMode of the object itself, Bad quality    -   AlarmMostUrgentInAlarm=FALSE, Bad quality    -   AlarmMostUrgentAcked=TRUE, Bad quality    -   AlarmCntsBySeverity={0, 0, 0, 0}, Bad quality

Also note that for an Object that is OffScan, all the Alarm Primitiveson that Object are forced to the state InAlarm=FALSE, so the Object doesnot aggregate its own alarms, which are all forced OFF. This is truewhether the Object has descendants or not. For Objects with descendants,the “bubble-up” operation takes place even for Objects that are OffScan.Consequently, the aggregation values represent the combined values ofthe Object and all its descendants.

If an Object with descendants is OffScan, its own internal aggregationvalues are the defaults with Bad quality. The value and quality of thecombined aggregation Attributes depend on whether the descendant Objectsare OnScan or OffScan:

-   -   If all of the descendant Objects are also OffScan, the combined        aggregation values for the parent are the default values with        Bad quality.    -   If some of the descendant Objects are OnScan, the combined        aggregation values for the parent include statuses and counts        from those descendants, but the combined aggregation Attributes        of the parent still have Bad quality.

If an Object with descendants is OnScan, then its own internalaggregation values are Good quality. Again, the value and quality of thecombined aggregation values depends on whether the descendant Objectsare OnScan or OffScan:

-   -   If all of the descendant Objects are also OnScan, the combined        aggregation values for the parent also have Good quality.    -   If some of the descendant Objects are OffScan, the combined        aggregation values for the parent have Uncertain quality. This        represents that these are a combination of Good values and Bad        values. This Uncertain quality propagates all the way up to the        Area level.

Alarm Aggregation for an individual Analog Field Attribute is stored inthe AnalogUtilities primitive that references the Field Attribute. Thedescriptions and statuses of the aggregation attributes are the same asfor those in the Common Primitive, except that they apply ONLY to theindividual Field Attribute and there is no overall InAlarm status forthe Field Attribute.

-   -   If there are alarms configured on a Field Attribute but none of        the alarms is in the InAlarm state or waiting to be Acked, the        same default values apply as for the Common Primitive with no        dependents.    -   If there are no alarms configured on a Field Attribute, then the        default values are the same as for the Common Primitive except        for AlarmMostUrgentMode, which remains Enable. This is because        there are no Alarm Primitives executing to copy the Object's        AlarmMode status to the Field Attribute's AlarmMostUrgentMode        attribute. The AlarmMostUrgentMode attribute retains its initial        value from start-up.    -   If the Object containing the Field Attribute is OffScan, the        aggregation Attributes for the Field Attribute are the same as        for an Object with no descendants, and all are default values        with Bad quality.    -   Aggregation statuses for Analog Field Attributes are not        separately “bubbled-up” from child Objects to parent Objects.        They are already part of the overall collection of alarms        configured on an Object, so they are “bubbled-up” as part of the        Object's aggregation values.

Alarm aggregation for an Area or pseudo-Area includes all the alarms (1)on the Area Object itself, (2) on all Objects assigned to the Area, (3)all descendants of those Objects, and (4) all sub-Areas directlyassigned to the Area in the Model View. The descriptions and statuses ofthe aggregation attributes are the same as for those in an Object, asthe same Common Primitive attributes are used.

Scan State and Data Quality for Alarm Aggregation Attributes of an Area:

The Quality for the alarm aggregation attributes on an Area is generallythe same as for Objects with descendants, with the followingdifferences:

-   -   If the Area is OffScan, the alarms configured on the Area itself        do not contribute to the Area's alarm aggregation values and are        of Bad quality, just as for an ordinary Object. So the overall        quality is Bad, with default values or combined values,        depending on whether all the Objects assigned to the Area are        OffScan or some of them are OnScan. But in addition, when the        Area is OffScan, the aggregation statuses of sub-Areas are NOT        retrieved in the post-execute phase. Even if those sub-Areas are        OnScan and available, their statuses and counts will not be        included in the parent Area's aggregation values.        -   Note: If a sub-Area is OffScan, even though it may have            bubble-up aggregation from its assigned Objects, the PARENT            Area will not be able to retrieve the aggregation attributes            from this sub-Area. So even if the parent Area is OnScan,            the parent's aggregation totals will NOT include the            bubble-up aggregation values of the sub-Area that is            OffScan. For quality information on the parent Area, see the            bullet item immediately below.    -   If the Area is OnScan, the aggregation values for the Area and        its Objects will have Good or Uncertain quality, depending on        whether all the Objects assigned to the Area are OnScan or some        of them are OffScan. But if the parent Area has one or more        sub-Areas from which it cannot retrieve aggregation statuses        (either because the sub-Areas are OffScan or communication has        been lost), the aggregation Attributes for the parent Area are        forced to Uncertain quality. This matches the behavior of the        long-existing Attributes for AlarmOnCntTotal, etc.        Enabled/Disabled Alarm Aggregation

Alarm Aggregation may be disabled or enabled at an Area Level. TheNotification Distributor primitive's “AlarmAggregationStateCmd” Booleanattribute will be true if aggregation is enabled and false if disabled.The default value of the attribute “AlarmAggregationStateCmd” is true,which means the Alarm Aggregation feature is enabled for a given area,and its child objects.

On Startup, the Area primitive will retrieve the value of the“AlarmAggregationStateCmd” Boolean attribute in its NotificationDistributor primitive. Based on the attribute's value, the area will dothe following:

-   -   If the value is true, all of the alarm aggregation functionality        described above will be performed.    -   If the value is false,        -   Area Object itself: Alarm aggregation functionality will not            be performed for alarms configured within the Area object            and attributes related to alarm aggregation must show            default value        -   Child Objects: Child objects of Area will not perform alarm            aggregation functionality and attributes related to alarm            aggregation must show default value.        -   Sub Areas: Area object will not subscribe to the alarm            aggregation values of sub area [pseudo area] even if Alarm            Aggregation is enabled at the sub area level.

User will be able to configure attribute “AlarmAggregationStateCmd” fromthe Area object editor. Platform/Engine/DI object editor will not havethe option to Enable/Disable Alarm Aggregation. Refer Area Object DFSfor detail. User will not be able to change the attribute value atruntime.

Because these are Attributes, the following statements apply:

-   -   They will always be accessible in every Object, because they are        part of the Common Object Primitive.    -   They will always be visible in Object Viewer, regardless of the        state of the various alarms on the Object and regardless of        whether the AlarmMode setting for those alarms (or for the        Object itself) is Enabled, Silenced, or Disabled.    -   It is also important to keep in mind that these are Attributes,        not alarms and not events—so they do not get registered with the        Notification Distributor or reported to the Distributed Alarm        System. They are not visible in clients such as the Alarm Viewer        Control and do not get logged by the Alarm DB Logger.    -   Other components such as SAL graphics must access these        Attributes by subscribing to them and/or performing        GetAttribute( ) operations.

As noted above, some objects and ArchestrA graphics symbols—such asthose in the Situational Awareness Library (SAL)—need an efficient andsimple way to identify whether any alarms on an Object currently needattention, what is the overall status of the most important of thosealarms, and how many alarms are presently active overall at each levelof severity. In addition, they need alarm aggregation to summarize allcontained Objects, following the Model View—so that the alarminformation represents the Object and all levels below it. This makes itpossible for a user to “drill down” from one level to the next and useaggregation to search for the underlying cause of a complex Object'salarms.

-   -   For an Object, aggregation represents the alarms on the Object,        on all contained Objects, and on their descendants, down to the        lowest levels of the Model View.    -   For an Area or pseudo-Area, aggregation represents the alarms on        the Area Object itself, on all Objects assigned to the Area, and        on all sub-Areas and their assigned Objects, down to the lowest        levels of the Model View.    -   For an Attribute, aggregation represents all the alarms on the        Attribute itself. This is the lowest level of aggregation.

In Summary, alarm aggregation takes a specific item that the user canpoint at within the hierarchy of factory hardware represented by objectsand indicates “within that object and all of the objects within thatobject, what is the most important or severe alarm that is happeningright now?” The alarm aggregation software instructions do not scan tofind the most urgent alarm; instead the instructions notify the nextlayer up proactively what the most severe alarm is. The objects areproactively reporting changes in its alarm state up the hierarchy.Previous methods were to go from the top down to check severity on everylittle component. Some of the alarms could be suppressed at a lowerlevel because there are different priority levels of alarms. The alarmseverity and whether the alarm has been acknowledged can affect whetherit is the most severe alarm.

Aggregation of Alarms for a Field Attribute:

Alarm Aggregation for an individual Analog Field Attribute is stored inthe AnalogUtilities primitive that references the Field Attribute. Thedescriptions and statuses of the aggregation attributes are the same asthose for an Object, except that they apply ONLY to the individual FieldAttribute and there is no overall InAlarm status for the FieldAttribute.

Propagation of Alarm Aggregation Through the Model View Hierarchy:

For the ArchestrA Application Server, all of the Objects in an Area areupdated once per Scan Cycle. During a Scan Cycle, all of the Objects areupdates using data values and alarm statuses that were finalized at theend of the PREVIOUS Scan Cycle. Then at the end of the Scan Cycle, thenew data output values are published and the alarm statuses are updated.They will be used as calculation inputs during the next Scan Cycle.

For Alarm Aggregation, during a Scan Cycle the aggregation statuses foreach Object and each Area are held unchanged. As each Object isexecuted, it generates a set of updated data and alarm statuses,including an internal set of updated alarm aggregation values thatrepresent the new statuses of the alarms. At the very end of the ScanCycle, a synchronization phase uses these internal aggregation values tocalculate the new alarm aggregation statuses for all AppObjects in anArea and for the Area itself, which will become the published alarmaggregation statuses for the next Scan Cycle.

-   -   Aggregation statuses for a Field Attribute apply only to the        Field Attribute itself. The internal aggregation statuses are        simply copied to the published aggregation statuses.    -   For each AppObject, the internal aggregation statuses for the        Object itself are combined with the updated aggregation statuses        of all of its child AppObjects, grandchild AppObjects, etc. to        produce the published aggregation status of the AppObject—which        represents the AppObject itself and all of its descendants in        the Model View Hierarchy.    -   For each Area, the internal aggregation statuses of for the Area        itself (as an Object) are combined with the aggregation statuses        of all its child AppObjects, grandchild AppObjects, etc. In        addition, Alarm Aggregation combines the status of the Area and        its AppObjects with the status of all sub-Areas under the Area        in the Model View Hierarchy. In this way, the aggregation        statuses of each Area represent the aggregation of all alarms in        the Area Object, all of its descendant AppObjects, and all of        its descendant sub-Areas.        Element Styles

As illustrated in FIGS. 1 and 5, also see the example of element stylesuser interface Appendix below, and FIGS. 9-17, a system manages humanmachine interface (HMI) applications for industrial control andautomation. FIG. 5 is a screen shot of an interface for specifying anelement style. In FIG. 5, the element style for an unacknowledgedcritical alarm is selected. The style includes text elements (Ts), fillelements (Fs) and line elements (Ls). It does not include outlineelements (Ol). There are no overrides as indicated in the previewwindow. Software instructions stored on a tangible, non-transitory mediaand executable by a processor receive data indicative of amanufacturing/process control system being monitored and display a userinterface indicative of a status of the manufacturing/process controlsystem being monitored wherein the status is based on the received data.In addition, instructions define a set of user-defined graphical elementstyle standards, granularly applicable to separate elements. Also,instructions responsive to user input configure a plurality of separateelements to be referenced to a particular graphical object representinga process control device of the manufacturing/process control systembeing monitored. The plurality of separate elements has the sameuser-defined graphical element style standards. The properties of theplurality of separate elements are defined by the particular graphicalobject so that the user configures the plurality of separate elementswithout accessing each of the plurality of separate elements. In variousembodiments, these instructions may be part of a system, and/or may bepart of software instructions stored on a tangible, non-transitory mediaand executable by a processor, and/or may be a processor executablemethod.

The graphic styles for all application elements in a galaxy arecentrally managed and distributed. This enables a user to change theappearance of an application element without going into the applicationelement and modifying specific properties of its graphic elements, forexample, colors, fonts or line.

Element styles comprises processor executable software instructionsstored on a tangible, non-transitory media (e.g., a memory device) andexecuted by a processor/server to provide a set of graphical elementstyle standards, granularly applicable to separate elements referencedto a graphical object representing a process control device, such as avalve within a pump. The style standards prevent the user from having tomodify colors or line widths manually. Any change to an element styleresults in an update to all references to the element style in the“galaxy”. User defined styles may be built upon default (predefined)styles. Instructions responsive to user input modify an element style ofthe particular graphical object and instructions change the elementstyle of the plurality of separate elements to have the sameuser-defined graphical element style standards as the modified elementstyle of the particular graphical object.

The keyword here is “standards”. Element styles are a way for users tocodify their graphic standards when it comes to color, line thickness,font, font color, line style, etc. The way this comes together is byexposing the ability for the user to utilize a set of standard stylenames (predefined). Some of these the user can change, and some arelocked down. Using our domain knowledge, the software recommends stylesfor the user's graphic elements to apply as is suggested by the styles.

The user can change aspects of the style (line thickness, font, fontcolor, etc.). The user can use the style name throughout the system inthe same way. Styles are provided and propagated in unique ways. Forexample, in one implementation, if the user have a pump, the pump mayhave 100 element styles. The user may want only the interior to go blackbased on one style. The user is provided with ways to granularly applythese styles to various elements. The user is also provided withdefaults for various styles. This allows the user to assign differentstyles to different parts of the pump.

The styles have an order of precedence within the styles themselves.They fall back on one another in certain situations. Styles can buildupon the existing styles that may be applied. In one form, these are not“cascading styles”. The styles have defaults and allow building onstyles. Upper level style changes are not pushed down to explicitly setstyles at the lower level, but it will push down to defaults.

Thus, the element style feature provides the ability for the user tocentrally manage the styles for all application in a galaxy. It enablesuser to change appearance of the application without going into theapplication and modifying specific properties of graphic elements, forexample, colors, fonts or line.

In one form, the element style feature provides a set of predefinedelement styles. These styles can be used as standard styles that can beapplied throughout the applications in the galaxy. A user is able tomodify the properties of the predefined styles for building a elementstyle to suit a need. A set of custom styles is also provided for theuser to create customized styles. The style library configuration dialogcan be launched from the IDE.

An element style can be exported from one galaxy and imported intoanother galaxy using the XML format. Validation is performed whenimporting an xml file to ensure the file contain the correct format.Thus, objects are groups into galaxies and a processor executesinstructions for exporting a user-selected element style of objects in afirst galaxy and for importing the user-selected element style into asecond galaxy using an XML format. The processor also executesinstructions for validating the imported XML file to ensure the importedXML file contains a compatible format with the second galaxy.

Whenever a user is changing the properties of the element style in thestyle library, the changes will be automatically be propagated to allruntime nodes so that the user does not have to redeploy theapplications.

To use the element styles defined in the style library, in the graphiceditor the user can configure the graphic element to use the styles fromthe style library. The user also use element style animation to applythe styles from the style library in runtime.

In summary, with the element style feature, the user has the ability toutilize preexisting element styles or custom element styles that can bereferenced in the user's graphics and animations. If the user changesthe properties of the element in the galaxy, all the graphics andanimations referencing the element style will be updated to reflect thechange.

FIG. 5 is a screen shot of an interface for specifying element styles.The styling of elements includes one or more of the following (See theexample of element styles user interface and FIGS. 9-17):

-   -   Font selection via a font selection dialog box;    -   Color section (color, gradient, pattern, textures) via a color        section dialog box 902, including an optional “no-fill” tab 904        as shown in FIG. 9.    -   Purpose    -   User Interface 1002 as shown in FIG. 10 providing various        configure options including “Galaxy Style Library.”    -   Launch Point    -   Element Styles user interface tab 1102 of the Configure Galaxy        Style Library interface as shown in FIG. 11, which indicates at        1104 that “no overrides” have been applied to element style        “Title” having text, fill and line features.    -   Quality and Status user interface tab 1202 of the Configure        Galaxy Style Library interface as shown in FIG. 12 indicating        line and outline communication error.    -   Behavior    -   Text style        Symbol Wizards

As illustrated in FIGS. 1 and 8, a system manages human machineinterface (HMI) applications for industrial control and automation.Software instructions stored on a tangible, non-transitory media andexecutable by a processor receive data indicative of amanufacturing/process control system being monitored and display a userinterface indicative of a status of the manufacturing/process controlsystem being monitored wherein the status is based on the received data.In addition, instructions define a set of designer-defined graphicalelement style standards, granularly applicable to separate elements.Also, instructions responsive to designer input configure a customizedsymbol wizard for use by the designer for generating symbols accordingto a customized, designer-defined template corresponding to at least oneof the designer-defined graphical element style standards. The softwareinstructions stored on a tangible, non-transitory media are executableby a processor. A processor executable method is provided. In variousembodiments, these instructions may be part of a system, and/or may bepart of software instructions stored on a tangible, non-transitory mediaand executable by a processor, and/or may be a processor executablemethod.

FIG. 8 illustrates one example of a component layout for a symbol wizardwhich enables user configurable encapsulation of process graphicfunctionality, which includes graphic elements, scripting and processvariables. The arrows indicate assembly references. A graphic editorcomponent 802 mainly contains the user interface for the graphic symbolsand provides a symbol wizard view. The graphic editor component 802indicates assembly references to a wizard option tree component 804 anda graphic library component 806. The wizard option tree component 804contains the user interface for configuring the wizard options. Thegraphic library component 806 is mainly used for rendering the graphicsduring runtime and design time. The graphic library component 806provides a wizard manager. The wizard option tree component 804 and thegraphic library component 806 indicate assembly references to a wizardoptions component 808. The wizard options component 808 contains thewizard option configurations and the option compiler.

In summary, the symbol wizard creator is a powerful and flexible toolthat allows a symbol wizard designer to create a complex, compositesymbol wizard that exposes a configuration that allows a subsequent userto configure objects/elements according to the subsequent user'sspecific needs within the parameters of the symbol wizard created by thesymbol wizard designer. Using the Symbol Wizard, subsequent users cancreate a customized symbol which has different locations of elementsthan other similar symbols within the parameters of the symbol wizardcreated by the symbol wizard designer.

Symbol wizards provide a configurable encapsulation of process graphicfunctionality, which includes graphic elements, scripting and processvariables. The symbol wizard comprises processor executable softwareinstructions stored on a tangible, non-transitory media (e.g., a memorydevice) and executed by a processor/server formatting a wizard generatordesigned to provide the user with modifiable symbol generators. Thesymbol wizard creator enables the design and modification of acustomized symbol wizard for generating symbols according to acustomized, user-defined template, which enables a higher level ofinvolvement from a user without the need for knowledge of objectoriented programming languages. The user is able to design each symbolwizard according to their own standards in terms of the elements,scripts, and process variables contained in each wizard.

A problem that users have faced in the past is that the user has lowlevel tools to build graphics, but the user who is assembling thegraphics for a particular application does not have the time or desireto use such low level tools to maintain a consistent design. The userwants to visualize things on the factory floor and has been give premadesymbols to use in the visualization. If they change a symbol, they havedrill down and get into lower, granular graphic levels to make theirchanges. The symbol wizard makes it easier to consistently createsimilar symbols for a particular application. For instance, with regardto a library-provided pump symbol, the user can configure whether thepump symbol displays a meter.

In the past, users have made change by modifying programming languagesand compiling the modified languages. At least some users have domainknowledge so that symbol wizards will allow them to craft their symbolswith more options they can change, without requiring programming. Symbolwizards also provide a tool for companies making their own symbols aswell. A high end user can use symbol wizards design, craft, deploy anddistribute the configurable wizards, and then another level of usershave the ability to use these symbol wizards to design the necessarysymbols. The wizard designer builds all the logic of each symbol wizardthrough click and point. Then the symbol wizards are handed-off to aapplication assembler who takes the symbol wizard from a toolbox ofavailable symbol wizards and uses them in their application.

The symbol wizard enables user configurable encapsulation of processgraphic functionality, which includes graphic elements, scripting andprocess variables. The symbol wizard functionality gives the symbolwizard designer the ability to create Graphic Symbol Wizards within theArchestrA Graphics Editor that can represent any number of uniquecombinations of Graphic Elements, scripts, and process variables as asingle symbol wizard.

This solves the problem of the designer being required to createmultiple symbols for a complex process graphic. The symbol wizardenables the designer to create a single symbol wizard which encapsulatesmultiple process graphics.

A user of the symbol can drag-and-drop the symbol onto the user'sdrawing canvas and configures the wizard instance to match the user'sspecific needs. Wizard Layers are a means to group process graphiccontents which define a specific subset of functionality to beencapsulated, which can be enabled conditionally through wizard rules.The contents of a layer will be included in the runtime environment ifit is enabled; otherwise, it is not included. This has the effect ofgreatly reducing the runtime system resource requirements andutilization on the visualization node.

Wizard Rules allow the designer to use wizard options 808 to constructBoolean logic statements which enable or disable layers. Wizard options808 are created by the designer to allow the Application Engineer toselectively enable or disable encapsulated functionalities within theSymbol Wizard. Choice Groups are created by the symbol wizard designerto group one or more, mutually exclusive choices. Choices are created bythe symbol wizard designer to represent a single configuration relatedto a subset of functionality within the process graphic. Options arecreated by the symbol wizard designer to represent a Boolean toggle of asingle configuration related to a subset of functionality within theprocess graphic.

In the graphic editor 802, the wizard designer is able to design andcreate options and choices for a particular symbol wizard through a userinterface. These options and choices will be exposed to a user of theparticular symbol wizard as optional configurations. The designer canhide or show the options and choices by configuring a rule expressionfor each option that will be evaluated to true or false.

A layer concept is also introduced in the graphic editor 802 to allowwizard designer to show and hide group of graphics and customproperties. The user can associate graphics to the layer by a drag anddrop function. Beside graphics, the user can also associate local customproperties and named scripts to the layers. Hiding or showing the layersis determined by the evaluation of the configured rule expression whichdriven by selection of choice or option that create by the wizarddesigner.

Trend Pen

As illustrated in FIGS. 1, 3A-3E and 4A-4F, a system manages humanmachine interface (HMI) applications for industrial control andautomation. Software instructions stored on a tangible, non-transitorymedia and executable by a processor receive data indicative of amanufacturing/process control system being monitored and display a userinterface indicative of a status of the manufacturing/process controlsystem being monitored wherein the status is based on the received data.In addition, instructions display graphic elements as part of the userinterface wherein each element is associated with and indicative of analarm status of one or more aspects of the manufacturing/process controlsystem being monitored. Also, instructions responsive to user inputrender a visualization window in a single trend line of blended dataincluding (1) received real time data of a process variable of themanufacturing/process control system being monitored and (2) historicaldata of the process variable of the manufacturing/process control systembeing monitored. In various embodiments, these instructions may be partof a system, and/or may be part of software instructions stored on atangible, non-transitory media and executable by a processor, and/or maybe a processor executable method.

A trend pen renders and enables visualization by a plant operator orother user of blended real time and historical data of a processvariable in a single trend with minimum configuration. One benefit isits extremely high performance and the ability to support 100's of trendpen elements displayed in a single process graphic window withoutperformance degradation.

Trend pen is a real time trend with historical backfilling with anyadditional data needed with historical data for a historian server todefine a single trend line, comprising processor executable softwareinstructions stored on a tangible, non-transitory media (e.g., a memorydevice) and executed by a processor/server providing a process variablevisualization tool, designed to provide the user with a depiction ofsimplified trend data which requires minimum configuration. The user isable to configure the time period and whether the window remains fixed,or moves as time progresses. Many other functional aspects of the toolare automatically configured, resulting in ease of access by the user.

For example, a user may have a level meter on a tank which changes inlevels over 2 hours. It's being filled. The user is not going to stareat that meter and remember what the rate of change was. The user wantsto just see a simple curve of where it's been in the last two hours. Thetrend pen is lightweight, does not have an x/y axis, and does not havelabels or scrollbars. It is a squiggly line that hangs off the side of ameter. Thus, real time trending is “heavy” on information.

A standard use case might be that a user has 10 tanks on a screen thatare holding oil. The system is able to provide a screen showing whereeach tank has been over a past time period. Data is typically collectedwhen the screen is open, but data is also collected in the historian.The trend pen will go to the historian and request the data from thedesired period at the desired granularity for visualization. Thus, theuser doesn't have to leave the screen up and running all the time.

When the trend pen screen is opened, it will determine what meters itneeds to figure out trending for, what time period to pull data from thehistorian, how many data points are necessary to be useful forpresenting a single line, what scale to use, etc. It presents it as asimple line that makes intuitive sense to the user based on what meteris being visualized.

The trend pen enables a plant operator or other user to visualize realtime and historical data of a process variable in a single trend withminimum configuration. It is a high performance process graphic elementthat displays the performance of a process variable over a short periodof time. Many trend pens can be displayed in a single process graphicwindow without performance degradation.

The trend pen element is configured to work with various type of meters,such as flow meter. A user of trend pen can drag-and-drop the trend penelement onto the canvas and attach a meter symbol to it. The trend penelement configuration option allows the user to configure processvariables to be monitored.

The trend pen automatically detects the historian server which attachesto the current platform. It makes a call in the background to retrievehistorical data for the configured process variable and render the trendbase on the historical data. This reduces the configuration effort sinceit may not know the name of the historian server. The trend will pick upthe real time data from the configured process variable and plot it onthe same axis together with the historical data for the configured timeperiod. The advantage is the user will see trending for both thehistorical and real time data based on the configured time period.

Trend pen allows two operation modes, one is a fixed window (AbsoluteTime Range) and the other is a moving or trending window (Moving WindowTime Range). The fixed window allows a user to enter a start and a endtime. The time range is automatically calculated for the moving windowmode.

A user is able to configure the time period for the trending window. Thetrend pen will retrieve the historical data based on the configured timeperiod. The trend pen exposes start time and end time properties whichare automatically calculated based on the time period. This allows usersto configure the starting in the fixed window mode. The refresh cycle isautomatically calculated based on the width of the trend penvisualization window (configured by the user) and the time period of thevisualization window. For example, the refresh cycle may be a percentageof the time period based on the width. As a specific example, it thewidth is one inch which corresponds to a 10% refresh rate and the timeperiod is one hour, then the refresh rate would be six minutes or 10% ofone hour. As another specific example, it the width is three incheswhich corresponds to a 5% refresh rate and the time period is 2.5 hours,then the refresh rate would be 7.5 minutes or 5% of 2.5 hours.

The trend pen provides users the ability to view real-time andhistorical data replay together on the same trend. One objective of thetrend pen is to provide additional information about the object (e.g.,meter or agitator) which allows users better understanding the behaviorof the process variable being visualized.

This trend pen is designed in such a way that a user only needs toperform minimum configuration. It will automatically detect the remotehistorian nodes where the process variable is historized. The trend penprovides the scalability and performance to have more than 100 to 200trends on single a window. This solves the problem of maintainingseparate trend for historian or real-time and cumbersome process ofpicking reference in each database. Users can update the targetreference and its period in runtime.

In the Absolute Time Range mode, a graphic symbol is shown for the firsttime, animation will get the data from historian based on the configuredstart time and end time. The data from that point in time forward isplotted using live data until the end time, as illustrated in FIGS.3A-3E. For example, FIG. 3A illustrates a plot from left to right of thedata 302 beginning 8:00 am as of 8:15 am. FIG. 3B illustrates a plotfrom left to right of the data 304 beginning 8:00 am as of 8:30 am. FIG.3C illustrates a plot from left to right of the data 306 beginning 8:00am as of 8:45 am. FIG. 3D illustrates a plot from left to right of thedata 308 beginning 8:00 am as of 9:00 am. As illustrated in FIG. 3E,trending halts at the end of a fixed time period 310 (e.g., 8:00 am to9:00 am). Thus, FIG. 3E illustrates a plot from left to right of thedata 312 between 8:00 am and 9:00 am as of 8:15 am. In this regard,instructions enable a user to configure a time period for thevisualization window wherein the visualization window comprises a fixedtime period having a start time and an end time specified by the user.

In the Moving Window Time Range mode, a graphic symbol is shown for thefirst time, trend tail animation will get the data from the historianbased on the configured time period. From that point in time forward,the trend is drawn using live data.

When getting data from Historian it will use,

-   -   Start Time=“Time when request is made—Period”    -   End Time=Time when request is made        -   The latest data will be shown on the Y axis. The simple            trend graphic element or animation will not draw any X axis            or Y axis as part of the visualization. The Y Axis referred            to here means anchoring of trend (which is configured using            a property of the trend element).            In the Time Period Configured mode, when getting data from            historian, it will get data based on the time period            configured. Initial trend data is captured and as time            passes the additional data is visualized so that the trend            line continues moving away from the Y-axis, falling off as            time passes. For example, see the illustrations in FIGS.            4A-4E. For example, FIG. 4A illustrates a plot 402 from            right to left of the data beginning time 1 ago and ending            now. FIG. 4B illustrates a plot 404 from right to left of            the data beginning time 2 ago and ending now. FIG. 4C            illustrates a plot 406 from right to left of the data            beginning time 3 ago and ending now. FIG. 4D illustrates a            plot 408 from right to left of the data beginning time 4 ago            and ending now. FIG. 4E illustrates a plot 410 from right to            left of the data beginning time 5 ago and ending now. Thus,            as illustrated in FIGS. 4D and 4E, the trend 412 continues            moving away from the y-axis, falling off at some time (e.g.,            “now −4”) as time passes. In this regard, instructions            enable a user to configure a time period for the            visualization window wherein the visualization window            comprises a moving time period which changes as time            progresses having a period of time specified by the user.            Thus, start time and end time properties for the            visualization window are determined based on the time            period.

The trend pen also supports clipping and auto out of range capabilitieswith shading area under the curve. FIG. 4F illustrates an exemplarylayout of trend pen components. A Galaxy Reference Manager component 424supplies a historian connector component 426 and a trend calculatorcomponent 428 with reference information. The historian connectorcomponent 426 and the trend calculator component 428 may be reused inthe INTOUCH system. A graphic library component 430 supplies thehistorian connector component 426 and the trend calculator component 428with a graphics library. The historian connector component 406 suppliesa historian client software development kit (SDK) component 432. Thehistorian SDK component 432 delivers a set of binary executables whichexpose a set of application programming interfaces (APIs) used by theTrend Pen animation to retrieve historical data, for the trended processvariable, from the historian data storage system. The historianconnector component 426 is responsible for managing connections tohistorian servers and to get history data from connected historianservers. The trend calculator component 428 is responsible forcalculating the trend plot points by taking into account the trendanimation parameters, runtime data and history data. It outputs an arrayof points that will be used by the simple trend graphic element torender a curve. The trend calculator component 428 is not dependent onthe other assemblies, except the required .Net Framework assemblies. Thegraphic library component 430 supplies a local message exchange (LMX)component 434 and an InTouch calibration component 436. The LMXcomponent 434 exposes a set of APIs and underlying services whichprovide access to locally cached process variables and system parametersat runtime, subscription services for real-time updates of the same, anda robust discovery capability at both design-time and runtime. The TrendPen animation utilizes the discovery service to find the source of thetrended process variable, then uses the subscription functionality toregister for real-time updates for the trended process variable. Otheroptional parameters include:

-   -   1. Trend Pen plots use Line (Slope) mode, as compared to a RT        (real-time) Trend having 4 options (Auto, Line, Step Line &        Point)    -   2. When historical data is not present, initial historical        plotting is BLANK in the trend pen, as compared to RT Trend        plots presenting a straight line.    -   3. When quality is BAD (e.g., below a minimum resolution), the        Trend Pen plots a BLANK graph, as compared to RT Trend plots        presenting a straight line with last known good value.

Thus, the trend pen is a powerful and flexible graphic element thatallows designers to build and use Single PV (Point-of-View) or multiplePV trends with applied element styles which can be either included aspart of existing graphics or shown as a pop up graphic to providehistorical and real time trends and to allow the user to make informeddecisions. This trend is primarily used by users to quickly understandthe historical and real time behavior of a PV to detect the situationand guide the user about the variability of the PV and is usually usedin meters (e.g., a flow meter, a miscellaneous meter, and a pressurecontrol meter) which are set of advanced process graphics in the symbollibrary.
